CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of and claims priority to U.S. patent application Ser. No. 12/893,971, entitled “Scrolling Virtual Music Keyboard,” filed on Sep. 29, 2010, the entire content of which are incorporated herein by reference.

FIELD

The following relates to scrolling a virtual keyboard on a touch screen device.

BACKGROUND

A traditional piano contains 7 octaves plus a minor third and 88 keys. A handheld wireless electronic device with a touch-sensitive screen input can run a virtual keyboard program that allows a user to play and record music. However, due to size dimensions of current devices only a fraction of a full 88-key keyboard is displayed on the touch-sensitive screen at a time. For example, an electronic device with a touch-sensitive screen input can display only one or two octaves of a musical keyboard at a time and still display keys that are large enough for ordinary users to play. However, users may wish to access other keys and octaves of a full 88-key keyboard for more options in creating sounds and music.

Current virtual keyboards on a handheld electronic device with a touch-sensitive screen input can allow a user to change the octaves displayed on the touch-sensitive screen by accessing a “+” or “−” button. For example, by pressing a “+” button, the user can cause the touch-sensitive display to show higher octaves, one octave shift higher for each press. Similarly, by pressing a “−” button, the user can cause the touch-sensitive display to show lower octaves, one octave shift lower for each press.

However, this implementation has limitations in that changes can only be made in octave increments. Also, the user must cease playing the keyboard, adjust the visible octaves using the “+/−” button, and then resume playing.

Therefore users can benefit from a method and system for scrolling a virtual keyboard on a touch screen device that allows a user to scroll the virtual keyboard to access other keys of the virtual keyboard, while playing the virtual keyboard. Users can further benefit from a method and system for scrolling a virtual keyboard on a touch screen device that scrolls to intelligent positions based on a key of a project, and that allows a user to hold a note that is no longer in contact with a user's finger due to scrolling.

SUMMARY

Disclosed are systems, methods, and non-transitory computer-readable storage media for scrolling a virtual keyboard on a touch screen device. A first aspect musical instrument keyboard interface for a touch-sensitive electronic display is disclosed. The interface includes a module for displaying a first musical instrument keyboard on the display, wherein the keyboard contains more keys than are simultaneously visible on the display. The first interface also includes a module for detecting a user contact swipe motion in a predetermined direction along the keyboard, for scrolling the keyboard across the display in accordance with the motion, and for stopping the scrolling upon termination of user contact swipe motion.

A second aspect allows scrolling of a virtual keyboard to snap to an intelligent position based on a song key or relative minor of the song key. A third aspect allows a note to be held when a user's finger remains in contact with the display even though the finger is no longer in contact with a key linked to the note on the keyboard as a result of scrolling. A fourth aspect displays a second musical instrument keyboard adjacent to a first musical instrument keyboard, wherein the second musical instrument keyboard is linked to the first musical instrument keyboard such that scrolling of one keyboard causes automatic scrolling of the other keyboard. Many other aspects and examples will become apparent from the following disclosure.

MIDI (Musical Instrument Digital Interface) is an industry-standard protocol that enables electronic musical instruments, such as keyboard controllers, computers, and other electronic equipment, to communicate, control, and synchronize with each other. MIDI does not transmit an audio signal or media, but rather transmits “event messages” such as the pitch and intensity of musical notes to play, control signals for parameters such as volume, vibrato and panning, cues, and clock signals to set the tempo. As an electronic protocol, MIDI is notable for its widespread adoption throughout the industry.

Furthermore, the keyboard is aligned based on a relative minor of an input musical key. In FIG. 6C, a module for receiving user input as to a musical key has received a user input that the musical key is C for this arrangement. The minor key of C is A. Also, in FIG. 6C, a module has aligned the keyboard 606 on the display 604 such that an end key visible on an end of the keyboard 606 is related to the relative minor of musical key input after stopping the scrolling. In this example, the module aligned the keyboard 606 on display 604 such that the A2 is in the left most position for keyboard 606. In this example, the module aligned the keyboard 606 in this manner because the A2 key was a predetermined distance from an edge of the display 604 upon termination of user contact swipe motion. This alignment allows a keyboard key corresponding to a relative minor of a key of a song input by a user to “snap to” the left most position of keyboard 606 after a user swipe if the keyboard key corresponding to the key of the song is within a predetermined distance from the left most position of keyboard 606.
